Title: Scintillation mitigation in geographically distributed satellite access nodes
Inventor: DANKBERG MARK
IPC: H04W24/04
Filed: 2018-01-25
Abstract: Systems and methods are described for scintillation mitigation in satellite communications systems with geographically distributed access nodes. Some embodiments operate in context of a bent-pipe satellite that illuminates user and gateway coverage areas with fixed spot beams. Beamforming can be used, along with coordinated, phase-synchronized communication by the distributed access nodes, to generate signals that coherently combine via the satellite. Scintillation and/or other atmospheric irregularities can degrade phase synchronization at the access nodes. Accordingly, embodiments can monitor phase tracking performance of the access nodes to detect when a phase tracking error occurs in at least one of the access nodes. In response to detecting the phase tracking error, embodiments can inhibit transmitting of forward uplink data signals by at least that access node.

Patent GB-1050882-A (GB)
IPC: B65H67/04
Abstract: 1,050,882. Drum-winding apparatus. W. REINERS. June 18, 1963 [June 22, 1962], No. 24201/63. Headings D1J and DID. A drum winding machine having automatic means for replacing a fully wound package with a fresh spool is provided with means which determine whether any residual winding exists on the fresh spool and which, if a residual winding is present, activate further means to tie the supply thread to the residual winding; if no residual winding is indicated the supply thread is clamped automatically on the tube and winding proceeds directly. The machine is also provided with a centering arrangement to allow for varying thicknesses of the residual windings and thus to ensure that the spool clamping device is correctly positioned on the spool axis. Thread F from a supply package A passes via a thread guide drum 22 to be wound on a package 21 having a spool 191. A magazine 155 holds a supply of spools S, some of which have residual winding R thereon and a feeler element 604 detects the presence of any such residual winding on the lowermost spool in the magazine. If a winding is indicated the element 604 closes a switch 605 and when the package 21 reaches a predetermined size a further switch 609 is closed completing a circuit to operate thread severing means 607, 608. Simultaneously upon completion of the winding of the package the drive thereto is interrupted and the package withdrawn by means of a bifurcated lever 169, 172 to the position 21' shown dotted. The magazine is pivoted into the position where the lowermost spool rests on the thread guide drum 22 and is clamped in that position. Sensing means (not shown) detect the absence of thread F due to the severing thereof and initiate a thread seeking a tying operation, by means, again not shown, whereby the supply thread is tied to the residual thread on the fresh spool. Normal winding now ensues. If no residual winding is indicated the thread severing means are not operated and when the completed package 21 is moved to the position 21' the thread extends thereto as indicated by the line F'. A guide lever 182 operates to draw the thread to the side of the fresh spool where it becomes clamped between the spool end and the spool clamping means. The stretch F' then breaks when normal winding recommences. As shown in Fig. 2, a counterweighted lever 612 is mounted with the clamping means 611 to ensure that, when lowered on to the fresh spool which rests on the thread guide drum 22 the clamping means are correctly centered on the spool axis. In the clamping operation the spool is shifted axially to prevent the lever 612 remaining in contact with the spool throughout the winding operation.

Abstract: 1,228,199. Semi-conductor device. WESTERN ELECTRIC CO. Inc. 2 Oct., 1968 [5 Oct., 1967], No. 46681/68. Heading H1K. In making a semi-conductor device a layer of semi-conductor material supported by a semiconductor body the thickness of which is to be reduced is provided beforehand with a metal supporting layer. In the manufacture of a Gunn diode a 5-25 Á layer of N-type gallium arsenide is epitaxially grown on an N + slice and covered by an N+ + layer. A thin layer of goldgermanium alloy is evaporated on and alloyed to the N+ + layer at 600 C. and then slowly electroplated with gold or silver to a thickness of 50 Á. Alternatively a foil of one of these metals is bonded on during the alloying step. The N+ slice is next reduced to a thickness of 5 Á by lapping. Alternatively it is completely removed and an N + + layer grown on the exposed face. In either case gold-indium alloy is evaporated on and alloyed to the resulting surface at 500 C. and is then slowly electroplated with gold or silver. The resulting assem. bly is sliced into individual devices by forming corresponding photoresist patterns on the opposed metal layers using a mask which is correctly aligned with the aid of apertures drilled through the assembly by a laser beam, and etching through the patterned photoresist first with an aqueous solution of iodine and potassium iodide to remove the metal and then in a sulphuric acid-hydrogen peroxide mix or an aqueous solution of bromine and methanol. Individual devices are thermocompression bonded to copper studs through gold or silver layers as shown in Fig. 4 and potted in silicone resin.

Curable amorphous terpolymers of two α olefins containing up to 10 carbon atoms and an orthocondensed polycyclic polyene substituted by at least one alkylidene group of which the double bond is conjugated with a double bond of a ring of the polyene, the polyene also being alkyl substituted on at least one carbon atom of the ring double bond conjugated with the double bond of the alkylidene group, may be prepared by copolymerizing the monomers in the presence of a catalyst. Specified olefins are C 2-6  olefins, and the polyene may be a methyl or ethyl substituted isopropylidene tetrahydroindene or hexahydronaphthalene. The catalyst may be derived from a transition metal of Groups IV to VIII, preferably a vanadium compound, and an aluminium compound AlR<SP>1</SP>X<SP>1</SP>X<SP>2</SP> where R<SP>1</SP> is H or C 1-10  alkyl, and X<SP>1</SP> and X<SP>2</SP> are H, halogen, C 1-10  alkyl or a secondary amine group, or a polyimino-alane. The catalyst may be formed in situ or in the presence or absence of at least one monomer, and the polymerization may be effected in an inert hydrocarbon liquid or excess of liquefied monomer. Examples describe the copolymerization of ethylene, propylene and (1) 1 - isopropylidene - 2 - and - 3 - methyl - 3a,4,7,7a - tetrahydroindene, (3) 1- isopropylidene - 2 - and - 3 - methyl - 1,4,5,8,9,10- hexahydronaphthalene and (5) 1 - isopropylidene - 2,3,4 - trimethyl - 3a,4,7,7a - tetrahydroindene in the presence of catalysts formed from diethyl aluminium chloride and (1 and 3) vanadium tetrachloride and (5) vanadium triacetylacetonate.

Abstract: 1,234,469. Knitting-machines. UNIVERSAL MASCHINENFABRIK DR. RUDOLF SCHIEBER G.m.b.H. 4 Sept., 1968 [12 Sept., 1967], No. 42008/68. Heading D1C. A flat-bed machine has narrowing mechanism including a control box on slide 22 which is carried by the cam carriage 10, but is arrested temporarily while narrowing occurs. The jacks are constructed with hooks (32 Fig. 3 not shown) engaging recesses (33) of adjacent jacks so that when jacks are manually moved to inoperative level 8 the batt of the last operative jack is moved to an intermediate level 9. The butt engages between fixed and pivoted cams 13, 11 on the carriage and forces the latter into engagement with two arm levers 16, 18 pivoted on the slide. The toothed end 23 engages the rack 2 and is held in this position, thus arresting the slide, by cam 25 of the carriage. The teeth are released by cam 27. A similar arrangement is provided to stop the slide when the carriage moves in the opposite direction.
